摘要
为了充分利用有关电力优惠政策,降低供热锅炉的运行费用,采用电锅炉蓄热技术,提出了临界峰谷电价比的概念和相应的计算方法,对电锅炉蓄热实际运行数据进行分析,并比较其与常规燃气供热锅炉的初投资及运行费用,得到临界峰谷电价的比值。计算分析表明,峰谷电价比大于临界峰谷电价比时,采用电锅炉蓄热供热比较经济合算,且投资回收年限随着峰谷电价比的增大而缩短。
The electric boiler storage technology is applied in order to make good use of elec-tric privilege policy and reduce the operating costs of heating boiler substantially.Putting forward the concept of critical peak-valley price ratio and the corresponding calculation method,through the analysis of actual operating data and comparing the initial investment and operating costs of the electric boiler heat storage with that of conventional gas heating boiler,we can get the ratio of critical peak-valley price .Calculation and analysis show that u-sing the electric boiler heat storage heating is economical and its investment recovery period along with the increase of the ratio of peak-valley price reduces when the peak-valley price is greater than the critical peak-valley price ratio.
